This repository contains three packages with Google integrations with LangChain:

• langchain-google-genai implements integrations of Google Generative AI models.
• langchain-google-vertexai implements integrations of Google Cloud Generative AI on Vertex AI
• langchain-google-community implements integrations for Google products that are not part of langchain-google-vertexai or langchain-google-genai packages

Each of these has its own development environment.

For full documentation, see the API reference. For conceptual guides, tutorials, and examples on using these classes, see the LangChain Docs.

See our Releases and Versioning policies.

As an open-source project in a rapidly developing field, we are extremely open to contributions, whether it be in the form of a new feature, improved infrastructure, or better documentation.
